The document outlines a lesson plan for 2nd grade students to learn about clouds. It breaks the students into four groups to research different aspects of clouds: formation, how they stay aloft, color variations, and movement. Each group will use provided links to online resources to research their assigned topic and create 2-5 slides for a class PowerPoint presentation. The groups will then present their slides to teach the class about clouds. The goal is for students to work collaboratively to gather information and share their new understanding of cloud formation and properties.
